Sure, but every change we make now means we diverge further from the well-tested
AArch64 port of 8u that's been shipping for some time.

I'm happy either way: Andrew already explained his plan with

"Just before rampdown is the best time to do this, as it always gives us
the option to roll back to this point, without losing other 8u282 changes.
This is what we also did with TLSv1.3. Such a rollback should be unnecessary
though, as this port has been in production for a long time!"
